Elastic sealing type sealing device for kiln head and kiln tail of rotary kiln

The invention provides an elastic sealing type rotary kiln head and tail sealing device. A flow guide isolation assembly is composed of a flow guide isolation movable ring and a flow guide isolation static ring, and the flow guide isolation movable ring and the flow guide isolation static ring are staggered and inserted to form a labyrinth sealing cavity; the sealing panel is sleeved on the supporting ring along the axial direction and is fixedly connected with the supporting ring; the elastic sealing mechanism is located in the sealing cover and arranged on the sealing panel in a sleeving mode, elastic components are arranged at the two ends of the elastic sealing mechanism, and a sealing ring with the tooth-shaped section is arranged between the two elastic components. The elastic sealing filler is located in the tooth-shaped groove. The air blowing pipe is mounted on the sealing cover, and the head end of the air blowing pipe extends out of the sealing cover and is communicated with an external high-pressu
